Looks like your graphics driver is sub-par
Can you install inxi and post results of command ---> inxi -GM

I get white text on a black background.

I assume you're getting black text on a black background, and I'm actually wondering if there's an issue with your GTK theme.

Create a new user account on your Linux system, try from there, and let us know if it's still a problem.

I disagree: this isn't an LQ issue. The code is using regular HTML title attributes, which isn't stylable in CSS, and thus the problem is not caused by the LQ forum software.
(It could theoretically be worked-around on the LQ side by re-implementing the title tooltip with JavaScript, but that wouldn't solve andrew's issue.)

My guesses would be GTK theme issue and/or a browser bug, so fits in "Linux - Software" or "Linux - General".

are you using a dark / black theme for your desktop ?

if so what you are seeing is likely a black box WITH BLACK TEXT

there is a firefox hack for this , that is if you are using firefox

pan64 · 03-04-2021, 09:39 AM

yes, it works for me too, so I guess that is a local problem on your host. (probably try another browser, reset browser, ...)

To confirm what was suggested in post #4 and repeated in #6, the text is there but is almost the same colour as the background (which is roughly #222527, so technically dark grey with a slight blueish tinge).

The very subtle difference between background and text is what allows this to be confirmed by using the magic wand tool in a graphics editor (as per attachment).

Yes, I am using firefox. I just tried with Dissenter Browser, it is fine.. black background, white text. so... it is theme vs firefox issue.

Dissenter browser works fine.. i guess it should be issue between theme and firefox.
Is there way to adjust the color of such text in theme ? in system setting > appearance ?

Wow! If in real world, or moderm world, You are Shellock homes, the detective ! LOL, How did you thought of that ? lol Brilliant..

How to change colors in Firefox (Support Mozilla).

Granted, this is only a stop-gap solution until you figure out what's wrong with your GTK theme.

elcore · 03-05-2021, 10:06 AM

GTK2 theme sets this with ntooltip_fg_color and ntooltip_bg_color.
GTK3, I don't know, probably with CSS. Rename ~/.config and ~/.themes + restart browser, and it'll revert to default theme.
It's not a forum problem, Lq had that exact same standard tooltip for as long as I remember.

Mine looks like this, it's using a GTK2 theme:

Heh, except I don't have a Dr Watson.

The background didn't look pure black to me, which raised a couple of possibilities:
* it's not uncommon for such backgrounds to be slightly translucent, whilst text is usually a solid, in which case even with the same RGB colour there could be a difference in the pixels rendered.
* if the values were independently chosen with a mouse, many GUI colour pickers don't have the precision/sensitivity to allow clicking the exact same position to get the same colour twice.

The selection confirmed there's no translucency, and there was more similarity to the colours then I'd expect for the second option, so there's probably another reason for the difference that I didn't think of.
